TECHNICAL FIELD

The present application relates to the technical field of smoking sets,and in particular relates to an aerosol generation apparatus and acontrol method therefor.

BACKGROUND

Articles (such as cigarettes, cigars, etc.) burn tobacco during use toproduce tobacco smoke. Attempts have been made to provide alternativesto these articles that burn tobacco by making products that releasecompounds without burning. Examples of such products are so-calledheat-not-burn products, also known as tobacco heating products ortobacco heating devices, which release compounds by heating a materialwithout burning the material. For example, the material may be tobaccoor other non-tobacco products or a combination, such as a blendedmixture which may or may not contain nicotine.

When a user smokes, a heater needing to be started to heat an aerosolgeneration substrate from an ambient temperature to an aerosolgeneration temperature that can form evaporant. The aerosol generationtemperature is generally 200° C.-400° C. In order to make the userexperience better and inhale the aerosol immediately or in time, it isnecessary to reach the aerosol generation temperature from the ambienttemperature within a short time, and power requirements for heating andpower supply components are very high, which may cause some problems.

Taking a heating rod of a key-activated resistive heater of a certainbrand as an example, when the user does not insert a cigarette into theheating rod, if a key is pressed or the key is touched by mistake, theheating rod starts the resistive heater for heating. In this case, theresistive heater is in a high temperature working state, there is nocigarette in the heating rod to conduct heat therefor, and a heatingcomponent is in a dry-burning state, which is easy to damage the heatingcomponent, resulting in a significant reduction in the service life ofthe heating rod.

FIG. 1 is a schematic structural diagram of an aerosol generationapparatus according to an embodiment of the present application.

As shown in FIG. 1 , the aerosol generation apparatus 10 includes abattery, 101, a controller 102 and a heater 103. In addition, theaerosol generation apparatus 10 has an interior space defined by ahousing, and an aerosol generation article (e.g., a cigarette) can beinserted into the interior space of the aerosol generation apparatus 10.

Only elements, related to the present embodiment, of the aerosolgeneration apparatus 10 are shown in FIG. 1 . Accordingly, it should beunderstood by those skilled in the art related to this embodiment thatthe aerosol generation apparatus 10 may further include general elementsin addition to those shown in FIG. 1 .

The battery 101 supplies electric power for operating the aerosolgeneration apparatus 10. For example, the battery 101 can supplyelectric power to heat the heater 103 and can supply electric powerneeded to operate the controller 102. In addition, the battery 101 cansupply electric power needed by a display, a sensor, a motor and thelike provided in the aerosol generation apparatus 10.

The battery 101 may be, but is not limited to, a lithium iron phosphate(LiFePO4) battery. For example, the battery 101 may be a lithium cobaltoxide (LiCoO2) battery or a lithium titanate battery. The battery 101may be a rechargeable battery or a disposable battery.

When a cigarette is inserted into the aerosol generation apparatus 10,the aerosol generation apparatus 10 heats the heater 103 by the electricpower supplied by the battery 101. The heater 103 raises the temperatureof an aerosol generation substrate in the cigarette to generate anaerosol. The generated aerosol is delivered to a user via a filter tipsection of the cigarette for smoking. However, the aerosol generationapparatus 10 can also heat the heater 103 even if the cigarette is notinserted into the aerosol generation apparatus 10.

The heater 103 may be in a central heating manner (being in contact withthe aerosol generation substrate by the periphery of a heating body orheating unit) or in a peripheral heating manner (the heating body or theheating unit wrapping the aerosol generation substrate), or the heater103 may heat the aerosol generation substrate by means of one or more ofthermal conduction, electromagnetic induction, chemical reaction,infrared action, resonance, photoelectric conversion, and photothermalconversion to generate the aerosol for smoking.

The controller 102 can control the overall operation of the aerosolgeneration apparatus 10. In detail, the controller 102 not only controlsthe operation of the battery 101 and the heater 103, but also controlsthe operation of other elements in the aerosol generation apparatus 10.In addition, the controller 102 can determine whether the aerosolgeneration apparatus 10 can be operated by checking the status of theelements of the aerosol generation apparatus 10.

The controller 102 includes at least one processor. The processor mayinclude a logic gate array, or may include a combination of a generalpurpose microprocessor and a memory storing a program executable in themicroprocessor. In addition, those skilled in the art should understandthat the controller 102 may include another type of hardware.

For example, the controller 102 can control the operation of the heater103. The controller 102 can control the amount of the electric powersupplied to the heater 130 and the time for which the electric power iscontinuously supplied to the heater 103 such that the heater 103 isheated to a predetermined temperature or maintained at an appropriatetemperature. In addition, the controller 102 can check the status of thebattery 101 (e.g., the remaining power of the battery 101) and, ifnecessary, can generate a notification signal.

In addition, the controller 102 can check whether the user smokes andsmoking intensity, and can count the number of smoked cigarettes. Inaddition, the controller 102 can check the time for continuous operationof the aerosol generation apparatus 10.

The aerosol generation apparatus 10 may include general elements inaddition to the battery 101, the controller 102 and the heater 103.

For example, the aerosol generation apparatus 10 may include a displayfor outputting visual information or a motor for outputting tactileinformation. For example, when the display is included in the aerosolgeneration apparatus 10, the controller 102 can send informationregarding the status of the aerosol generation apparatus 10 (e.g.,whether the aerosol generation apparatus 10 can be used), informationregarding the heater 103 (e.g., preheating start, preheating inprogress, or preheating complete), information regarding the battery 101(e.g., the remaining power of the battery 101, whether the battery 101can be used), information regarding reset of the aerosol generationapparatus 10 (e.g., reset time, reset in progress, or reset complete),information regarding cleaning of the aerosol generation apparatus 10(e.g., cleaning time, need to clean, cleaning in progress, or cleaningcomplete), information regarding charging of the aerosol generationapparatus 10 (e.g., need to charge, charging in progress, or chargingcomplete), information regarding smoking (e.g., the number of smokingtimes and smoking end notification), or information regarding safety(e.g., use time) to the user. Alternatively, when the aerosol generationapparatus 10 includes the motor, the controller 102 can generate avibration signal by using the motor and can send the informationdescribed above to the user.

In addition, the aerosol generation apparatus 10 may include at leastone input device (e.g., a key) used by the user to control functions ofthe aerosol generation apparatus 10. For example, the user can performvarious functions by using the input device of the aerosol generationapparatus 10. The desired function among the plurality of functions ofthe aerosol generation apparatus 10 can be performed by adjusting thenumber of times the user presses the input device (e.g., once or twice)or the time the user continues to press the input device (e.g., 0.1 s or0.2 s). As the user operates the input device, the aerosol generationapparatus 10 can perform the function of heating the heater 103, thefunction of adjusting the temperature of the heater 103, the function ofcleaning a space into which the cigarette is inserted, the function ofchecking whether the aerosol generation apparatus 10 can be operated,the function of displaying the remaining power (available electricpower) of the battery 101, and the function of resetting the aerosolgeneration apparatus 10. However, the functions of the aerosolgeneration apparatus 10 are not limited thereto.

FIG. 2 is a schematic structural diagram of a cigarette according to anembodiment of the present application.

As shown in FIG. 2 , a cigarette 20 includes a filter tip section 21 anda tobacco section 22.

The tobacco section 22 includes an aerosol generation substrate. Theaerosol generation substrate is a substrate capable of releasingvolatile compounds that can form an aerosol, and the volatile compoundscan be released by heating the aerosol generation substrate.

The aerosol generation substrate may be a solid aerosol generationsubstrate. Alternatively, the aerosol generation substrate may includesolid and liquid components. The aerosol generation substrate mayinclude a tobacco-containing material containing volatile compounds witha tobacco flavor which are released from the substrate upon heating.Alternatively, the aerosol generation substrate may include anon-tobacco material. The aerosol generation substrate may furtherinclude an aerosol generation substance. Examples of suitable aerosolgeneration substances are glycerine and propylene glycol.

The aerosol produced by heating the tobacco section 22 is delivered tothe user via the filter tip section 21, and the filter tip section 21may be a cellulose acetate filter tip. The filter tip section 21 can besprayed with flavoring liquid to provide fragrance, or separate fiberscoated with the flavoring liquid can be inserted into the filter tipsection 21 to improve the durability of the flavor delivered to theuser. The filter tip section 21 may also have a capsule of a sphericalor cylindrical shape, which may contain the contents of flavoringsubstances.

Only the components, related to the present embodiment, of the cigarette20 are shown in FIG. 2 . Accordingly, those skilled in the art relatedto this embodiment should understand that the cigarette 20 may furtherinclude general components in addition to those shown in FIG. 2 , e.g.,a cooling section for cooling the aerosol produced by heating thetobacco section 22, such that the user can inhale the aerosol cooled toa suitable temperature.

FIG. 3 is a schematic diagram of a preheating curve of a heateraccording to an embodiment of the present application.

As shown in FIG. 3 , a temperature curve of the heater 103 over timeincludes a heating phase and a heat preservation phase.

In the heating phase, the temperature of the heater 103 is raised froman initial temperature T0 (or an ambient temperature) to a preset targettemperature T1. The preset target temperature T1 is set such that thedesired volatile compounds vaporize from the aerosol generationsubstrate, and undesired compounds with higher vaporization temperaturesdo not vaporize. Generally, the preset target temperature T1 may be 200°C.-400° C.

In the heat preservation phase, the temperature of the heater 103 ismaintained at the preset target temperature T1 for a period of time,such that the aerosol generation substrate is sufficiently preheated andthe smoking feeling of the user is improved.

The duration of the heating phase is t0-t1, the duration of the heatpreservation phase is t1-t2, and t0-t2 is a preheating time of theheater 103. Generally, the preheating time of the heater 103 is 5 s to30 s.

It should be noted that FIG. 3 only shows a schematic diagram of atemperature curve related to this embodiment. Those skilled in the artshould understand that, generally, after the heat preservation phase,the heater 103 is in the smoking phase, that is, the user can smoke theaerosol generated by heating of the aerosol generation apparatus 10. Inthis phase, the temperature of the heater 103 is maintained within acertain preset temperature range or at a certain preset temperature fora period of time.

FIG. 4 is a schematic flowchart of a control method for an aerosolgeneration apparatus according to an embodiment of the presentapplication.

As shown in FIG. 4 , in step S11, a controller 102 determines totalenergy generated by heating of a heater 103 within a preset time.

The preset time may be determined according to a preheating time of theheater 103. As shown in FIG. 3 , the preset time is greater than orequal to duration t0-t1 when the temperature of the heater 103 risesfrom an initial temperature to a preset target temperature.

Furthermore, the preset time is less than or equal to the preheatingtime t0-t2 of the heater 103.

The preset time is capable of being divided into one or more heatingtime periods according to heating power of the heater 103. Thecontroller 102 determines energy generated by heating of the heater 103within each heating time period according to the heating power of theheater 103 corresponding to each heating time period within the presettime, and then obtains the total energy generated by heating of theheater 103 within the preset time according to the energy generated byheating of the heater 103 within each heating time period.

As an example, if the preset time is the preheating time t0-t2 of theheater 103, in the heating phase t0-t1 of the heater 103, the controller102 controls the heating power (assuming the power is constant) suppliedby a battery 101 to the heater 103 to be W1; and in the heatpreservation phase t1-t2 of the heater 103, the controller 102 controlsthe heating power (assuming the power is constant) supplied by thebattery 101 to the heater 103 to be W2. The energy generated by heatingof the heater 103 in the heating phase t0-t1 is Q1=W1*(t1−t0), and theenergy generated by heating of the heater 103 in the heat preservationphase t1-t2 is Q2=W2*(t2−t1). Therefore, the total energy generated byheating of the heater 103 within the preset time is Q3=Q1+Q2.

In step S12, the controller 102 performs dry-burning detection accordingto the total energy generated by heating of the heater 103 within thepreset time.

Specifically, the controller 102 compares the total energy generated byheating of the heater 103 within the preset time with a preset energythreshold, if the total energy generated by heating of the heater 103within the preset time is less than the preset energy threshold,determines that dry-burning occurs; and otherwise, determines that nodry-burning occurs.

The preset energy threshold may be an experimental value or empiricalvalue. For example, the heater 103 is used to preheat a cigarette 20 ofa certain type, and the total energy Qn generated by the heater 103heating such type of cigarette 20 within the preheating time t0-t2 istested, and after several tests, an average value is obtained to serveas the preset energy threshold.

When it is determined that dry-burning occurs, the controller 102controls the heater 103 to stop heating, so as to prevent the heater 103from being in a dry-burning state all the time, resulting in damage tothe heater 103. Furthermore, the user can be prompted that the heater103 is in the dry-burning state by means of an indicator lamp orvibration.

When it is determined that no dry-burning occurs, the controller 102controls the heater 103 to continue to perform the next phase, e.g.,completing the heat preservation phase, entering a smoking phase, and soon.

FIG. 5 is another schematic flowchart of a control method for an aerosolgeneration apparatus according to an embodiment of the presentapplication.

As shown in FIG. 5 , in step S21, in a heating phase t0-t1, a controller102 controls a heater 103 to perform heating with first heating power.

In this step, the controller 102 controls the heater 103 to performheating with constant heating power, and the first heating power may bethe maximum heating power supplied by a battery 101 to the heater 103under the control of the controller 102.

Generally, during the heating process of the heater 103, a resistancevalue of the heater 103 may change with the change of temperature,resulting in that the heating power supplied to the heater 103 alsochanges. Therefore, furthermore, the controller 102 can also control theheater 103 to perform heating with the constant heating power by thefollowing steps:

determining a real-time resistance of the heater 103; determining areal-time voltage supplied to the heater 103 according to the real-timeresistance of the heater 103 and the first heating power; and adjustinga voltage supplied to the heater 103 to the real-time voltage.

Specifically, if the real-time resistance of the heater 103 is R1 andthe first heating power is W1, the real-time voltage U₁=√{square rootover (W1×R1)} supplied to the heater 103 can be calculated by formula:W=U²/R, and then the voltage supplied to the heater 103 is adjusted tothe real-time voltage U₁.

The real-time resistance of the heater 103 can be determined bymeasuring the voltage applied to the heater 103 and the current flowingthrough the heater 103.

In step S21, in the heat preservation phase t1-t2, the controller 102controls the heater 103 to perform heating with second heating power,and linearly adjusts the second heating power according to a presettarget temperature T1, where the second heating power is less than thefirst heating power.

Specifically, the controller 102 determines the real-time resistance ofthe heater 103, and determines a real-time temperature of the heater 103according to the real-time resistance of the heater 103. When thereal-time temperature of the heater 103 is less than the preset targettemperature T1, the second heating power is linearly increased accordingto a first preset step value. When the real-time temperature of theheater 103 is greater than the preset target temperature T1, the secondheating power is linearly decreased according to a second preset stepvalue.

During the heating process of the heater 103, the resistance value ofthe heater 103 changes with the change of temperature. The resistancevalue and temperature of the heating unit 101 can form a correspondingrelationship between the resistance value and the temperature, anddifferent temperatures correspond to different resistances. Therefore,the real-time temperature of the heater 103 can be determined bydetermining the real-time resistance of the heater 103.

Optionally, the first preset step value and the second preset step valuemay be the same.

It should be noted that, similar to FIG. 3 , FIG. 5 only shows theschematic flowchart of the control method for an aerosol generationapparatus related to this embodiment. Those skilled in the art shouldunderstand that, generally, after the heat preservation phase, theheater 103 is in the smoking phase, that is, the user can smoke theaerosol generated by heating of the aerosol generation apparatus 10. Inthis phase, the controller 102 controls the temperature of the heater103 to be maintained within a certain preset temperature range or at acertain preset temperature for a period of time.

To better illustrate the present embodiment, the control process of theaerosol generation apparatus is explained below:

After the aerosol generation apparatus 10 starts for preheating, thecontroller 102 controls the heater 103 to enter the heating phase.Specifically, the controller 102 can control the heater 103 to performheating with the constant heating power of 6 W. During the heatingprocess of the heater 103, the resistance value of the heater 103 maychange with the change of temperature, resulting in that the heatingpower supplied to the heater 103 also changes. Therefore, the controller102 determines the real-time resistance of the heater 103, determinesthe real-time voltage supplied to the heater 103 according to thereal-time resistance of the heater 103 and the constant heating power of6 W, and adjusts the voltage supplied to the heater 103 to the real-timevoltage.

When the heater 103 is controlled to be heated to 350° C. (or 340°C.-360° C.), the controller 102 controls the heater 103 to enter theheat preservation phase. Specifically, the controller 102 controls theheater 103 to perform heating with power less than the constant heatingpower of 6 W, for example, the heating power of 4 W. At the same time,the controller 102 determines the real-time resistance of the heater103, and determines the real-time temperature of the heater 103according to the real-time resistance of the heater 103. When thereal-time temperature of the heater 103 is less than 350° C., theheating power of 4 W is linearly increased according to the preset stepvalue of 0.05 W, that is, the controller 102 controls the heater 103 toperform heating with the power of 4.05 W, so as to reduce thetemperature of the heater 103 and maintain the same at 350° C. When thereal-time temperature of the heater 103 is greater than 350° C., theheating power of 4 W is linearly decreased according to the preset stepvalue of 0.05 W, that is, the controller 102 controls the heater 103 toperform heating with the power of 3.95 W, so as to raise the temperatureof the heater 103 and maintain the same at 350° C.

The above preheating time is generally 20 s. After preheating ends, thecontroller 102 determines the total energy generated by heating of theheater 103 within the preheating time, and compares the total energygenerated by heating of the heater 103 within the preheating time with apreset energy threshold, if the total energy generated by heating of theheater 103 within the preset time is less than the preset energythreshold, determines that dry-burning occurs; and otherwise, determinesthat no dry-burning occurs.

When it is determined that dry-burning occurs, the controller 102controls the heater 103 to stop heating, so as to prevent the heater 103from being in a dry-burning state all the time, resulting in damage tothe heater 103. Furthermore, the user can be prompted that the heater103 is in the dry-burning state by means of an indicator lamp orvibration.

When it is determined that no dry-burning occurs, the controller 102controls the heater 103 to entering a smoking phase, and prompts theuser to smoke.
